Abstract: A stocking or sock with a foot portion includes a pocket for containing the big toe that is separate from the pocket(s) for the other toes. At least one medial reinforcement, integrally attached to the foot portion, entirely or partially surrounds the big toe pocket, while the medial part of the foot portion, and the posterior part or heel of the foot portion are anchored to the posterolateral or lateral part of foot portion, coming to bear on the anterior part of said pocket, counteracting any lateral deflections, and on the medial part, corresponding to the metatarsophalangeal joint and the first metatarsal of the foot, counteracting any medial deflections.
